Rapid application development using agile methodologies and processes are increasingly being used when developing applications. There is pressure on development teams to reduce the time needed to convert an idea into a working solution, be it as part of an innovation workshop or hackathon, a prototype for a new solution idea or main stream development.
Developers are looking for new ways to allow them to be more production and innovations, such as Node-RED from the JS Foundation is a technology that allows a developer to rapidly create applications, taking a fraction of the time need coding write code.
Node-RED is built on Node.js, so will run anywhere capable of hosting node.js applications, such as small single board computers like the Raspberry Pi or Beaglebone, on your laptop or workstation or in cloud environments, such as the IBM Cloud.
Node red allows developers to compose flows using a pallet of nodes, where each node provides prebuilt functionality, that can be connected to other nodes to rapidly construct an application.
This course assumes some basic knowledge of Node-RED, so if you have not used Node-RED then you may want to take a look at the Coursera course - A Developer’s Guide to the Internet of Things (https://www.coursera.org/learn/developer-iot/), which provides a beginner look at Node-RED.
What you will learn:
The course will improve your use of Node-RED. It will introduce some more advanced features available in key nodes, show you how to visualise data using dashboard nodes. It shows you how to create web APIs using Node-RED and how to consume web services and how to make use of different storage technologies within a Node-RED flow. The last section of the course shows how you can extend Node-RED by creating your own nodes.
What technology is required to complete the course?
The course requires you to have an IBM Cloud account, as some of the assignment work does make use of designated cloud services. You can create a free account on the IBM Cloud and in week 2 of the course we make a promotional code available, which unlocks some additional resources on the IBM Cloud, so you can complete the course without having to provide credit card information or pay for cloud services.
If you choose to take this course and earn the Coursera course certificate, you will also earn an IBM digital badge. To find out more about IBM digital badges follow the link https://ibm.biz/badging.

From the lesson

Week 1 - Introduction and Review of Node-RED

Welcome to the course. This learning module introduces you to course and the instructors. The module outlines the content covered on the course and gives an introduction to the Internet of Things. It also discusses the requirements needed to complete the course including the hardware, software and details of prerequisite skills required to complete the programming assignments.
The module then discusses using Node-RED to create cloud applications and the different options available to customise the Node-RED runtime
